Figure 15 Mounting Bolt Location in Cross Arm

Grounding the WXT520

The normal way to ground the WXT520 is to install it on a mast or a

cross arm that provides a good connection to earth ground. The

grounding is provided via the fixing screw (or mounting bolt), so it is

important that it makes a good ground connection. If the surface of the

mounting point is painted or has some other finishing that prevents a

good electrical connection, consider using the Bushing and Grounding

Kit and a cable to provide the ground connection.

Grounding Using the Bushing and Grounding Kit

If necessary, you can run a cable from the fixing screw to a grounding

point. A Bushing and Grounding Kit (Vaisala order code: 222109) is

available for this purpose. The kit includes a longer fixing screw, two

nuts and washers, and an Abiko connector for the grounding cable.

Refer to Figure 16 on page 39 for an illustration on how to assemble and

install the kit.

The following numbers refer to Figure 15 on page 38:
